| 620 Sport Help
Hi,
I’ve recently picked up a 620 Sport to join in the DD fun next year (great track selection by the way, well done Chris and mt).
I’d like to refresh my forks with new oil but the previous owner doesn’t know what weight is in there at the moment and suggested I try the forum.
So is the standard recommended 7.5 oil good enough for race/track use, or do I need to try something abit heavier ie 10, 12.5, 15 etc? |
